Been vaping the with the Kanger tanks for a the last few months. Have a few cheapo RBA's, and have no qualms about recoiling and wicking, but it seems a bit overwhelming with the amount of tank fed RBAs on the market. Been looking at the AGA T2, and the Kayfun, even the Promethius. Anyone have any advice or experiences they can help me out with in making a decision... or 2?
